i lower wing, 13,01: each of these hinges is,

inad'e wider 'than :is necessary in order 'to overhang the inside edgeof the movable rail, 4. In fact, these wings, 13, are preferably madewide enough to cover the top edges of both lthe back rails, B and 4. The

rthere is'slidably mounted a stem shown at 15, each stem being rigidlyattached to the overhanging .portion .of the wings, 13. Thus,

. as the seat, 7, is loweredI after thewings, 9,

.have ,been elevated, the back rail, 4, is per- 'm-itted a .truevertical-movement by being f"guided :by means lof the stems, 15,"sliding'within the bushings, 14. It will, therefore,

Japp'ear thatftherear rail, 4, is movable between an upper anda lowerposition `and i in this way, the .appearance of the rear port-i'onof thebenchis maintained uniform. It will also be noted that this rear rail,4,

J x'sl-idesin a .true vertical direction 'and does not'assume aninclined position whenat-the upper Iend fof its movement. n

In order to cause the automatic yelevation .of these'.wings, 9, upon thelmovement of the `',30seat, 7'; to'its'elevated position, I have alsomounted these wings, 9, so that they are slidazble to a `slight extenton their supporting. rods, 8.

In addition, teach of these supporting vwings isy cut out as shown atfl6to permitthe 'application' of a torsion spring, 17, one end of whichis`rigidly secured toeach of,v the ,supportfrods l8, andthe opposite endof each of whichas is shown at 18 is Vmade to engage .respective `wingto normally force 'the wings totheir lowerniost position. f

Mounted on the loutside face of each of the wings is a rod, 19, onwhich' the sleeve, 2K0, is slidably mounted.'

sleeves, 20, will have engaged the shoulders, 25, forming one end of thecut out portions, 22, and will also have moved these wings totheirrearmost position of movementgtfas is indicated in F ig. 2. i l M`The vinsideback rail, 3, is provided adjacent each wing, 9 with a, stopstructure 75 shown at 26 whichfforinsstallsinto "which the wings,9,`arefmoved when intheir elevated position as has just-been described;These stops are kprovided, in order` to prevent the return of ,the wingsto theirl hori 'zontal fpositionl when it 'isjatternpted to lower theseat, 7,- which movement wouldlbecaused bythe torsionp'fthe"springs,1'7';V

Howevenbefore the seat, 7 has reached- 'a lower upper inclined position,the sleeves,

` In order to further guard against theA low- -ering' of the wings 5during the operation; of lowering the seat, l7,1 have notched out theinside face ofthe seat where engages'each 100)` wing is' shown in dottedlinesat 27 in Fig. 2 and from this it will follow. that itisfthe vn'otches 27 which rst engage the wings, k9, at

During the act of lowering seat, 7, each of the wings will be movedout of engagement with the stops, 26, but will be prevented from fallingunder the influence of the spring 17, by being engaged with the underside-of the seat, 7. However, a subsequent elevation of the seat, 7, toa position slightly higher than that indicated bythe dotted lines inFig. 2 will permit'these wings to drop by means ofthe springs 17. Duringthis subsequent elevation of the seat, therear rail, 4, will dropvertically because of its slidable connection with the rail, 3, and ifthen the seat,'7, is again lowered, the latter will assume the positionas indicated in Fig. 3.

It will thus appear that comparatively simple means are provided foraccomplishing the objects ofthe invention. In addition, the structure isnot complicatedy to such a degree as will render its operationuncertain.
